There was no difference in implant cut-out, deep surgical site infection or peri-implant fractures. Patients treated in the SN cohort experienced shorter operative times but did not differ in tip-to-apex distance or subtrochanteric fracture extension. There was a clinically insignificant difference in the HHS between cohorts. SN and LN cohorts were comparable in all aspects of the SF-36. Secondary outcomes included implant failure, peri-implant fracture, mortality, operative time, estimated blood loss (EBL) and reoperation. The primary outcome measurement was functional outcome evaluated by Short Form (SF-36) and Harris Hip scores (HHS) at 3 months. Demographics were comparable between cohorts. Fifty-two patients did not meet minimum 3 month follow up. A total of 168 patients (SN, n=80 LN, n=88) had a mean follow-up of 13.9 months. Two-hundred and twenty patients with intertrochanteric fractures were prospectively randomized to a SN or LN. To compare functional and clinical outcomes in patients with pertrochanteric hip fractures treated with either a short (SN) or long (LN) cephalomedullary nail.Ĭlinical investigation was performed at the Mayo Clinic's Level 1 Trauma Center in Rochester, Minnesota.
